What causes volcanoes to erupt?

• They ate bad clams.

• The pressure of convection currents moving plates forces the eruption.

• Volcanoes form to create new islands.

• The liquid core is extremely hot causing eruptions

The lithosphere includes which layers of Earth?

• The lower mantle and the outer core

• The inner and outer core

• The crust and upper mantle

• The upper mantle and lower mantle

The image shows a mid ocean ridge. What is an important feature of seafloor spreading?

• Mid ocean ridges only occur at convergent boundaries.

• The convection currents in the core drive the plates apart.

• As the plates pull apart, the lava rises to form new crust.

Which answer best compares earthquakes and volcanoes?

• Volcanoes are on the surface and earthquakes are beneath the surface.

• The pressure of the earthquake always causes a volcano to erupt.

• Tectonic plate movement plays a role in the formation of volcanoes, but has nothing to do with the strength of earthquakes.

• Volcanic activity can cause earthquakes

Before the theory of plate tectonics came to be,

• Scientists drilled to the center of the Earth to see what was happening.

• Scientists discovered seafloor spreading which lead to the concept of continental drift.

• Scientists dated fossils from different animals.

• scientists measured ice caps to see if they decreased in size.

Which best describes Earths outer core?

• It is located between the lower mantle and the inner core.

• It is solid iron

• It is liquid water

• It is hotter than the inner core.

How do scientists study Earths structure?

• Drilling to the center of the Earth.

• Using seismic waves to map and collect data.

• By following a lava flow to a volcano.
